Abstract:

The flow about an unyawed cone is considered for the hypersonic moderately low density regime. The shock wave boundary layer interaction is considered in the context of the hypersonic strong interaction approximation. Small transverse curvature and small surface slip effects are considered as perturbations on the basic strong interaction solution. Solutions of the governing two-point boundary value problem are obtained by reduction to a system of ordinary differential equations using double asymptotic expansions in a slip parameter and a hypersonic transverse curvature parameter which is proportional to M sq. times the Probstein and Elliott transverse curvature parameter. Previous solution for Pr1.0, gamma1.405 are extended to the cases of Pr0.723, gamma1.405 and Pr1.0, gamma1.67. The specific effects of non-unit Prandtl number and increased ratio of specific heats zeroth-order pressure gradient on the zeroth-order, first-order slip and first-order transverse curvature induced surface pressure, boundary layer displacement thickness, skin-friction and wall heat transfer rate are discussed.
